Hi!
Regarding the two middle names, I don't think two is too many. For most of my girls combos I have two middle names, I love the way they flow. Sometimes that second middle name can really add a pretty touch. I have two middle names, so do some of my cousins, my sibling, some of my friends, family members, etc. Then how to honor a Derek- I think you should look up the meaning. For example, if the meaning of Derek is strong, a name with a meaning along those lines would work- another name meaning strong, or powerful, etc. anyways, congratulations and good luck!

Personally, I feel it's too many. You hardly ever use 1, what's the point of 2? But it's just a personal preference. However, I feel if you do choose to do 2, then you should continue to use 2 on your next child/ren

I have 2 middles and my husband has 2. My full name is AimeeLoisBoden [last name]. Lois is my grandma's name and Boden is my mums maiden name. I've never had a problem with it. When I'm asked to write my middle name, I write both and if there isn't enough room then I just write AimeeLois. We gave our angel baby two middles too and we will do for our next child.

I'm not a fan of the double middle name. I think, if you want to honor your husband's father, you should just take what you can from Derek and not saddle your child with two middle names-- especially if you don't even like one of them!

Of course, there's always the option of taking the first letter "d" and doing something with that. Seeing as your choices are pretty limited, I'd probably do that. OR if that's not an option, find out more about Derek. Does he have a middle name? A favorite hobby? Find out everything you can about your father-in-law and apply that to your name search. Sometimes a disguised meaning can be more meaningful than a blatant sharing of a given name.
